Dr. Ernesto Torres said doctors have finished performing all medical tests on Camacho, who was shot in the face Tuesday night.

"We have done everything we could," said Torres, who is the director of the Centro Medico trauma center in San Juan. "We have to tell the people of Puerto Rico and the entire world that Macho Camacho has died, he is brain dead."

He said at a news conference that the family expects to say by Friday if Camacho should remain on life support.

Camacho was shot through the jaw on Tuesday night as he sat in a Ford Mustang with his friend, Adrian Mojica Moreno, who was killed. According to the Associated Press report, there was cocaine found in the car.

No arrests have yet been made in the shooting. Puerto Rican police believe there were two gunmen, who fled the scene in an SUV.

Camacho was a former champion in three different weight divisions and finished his career with a 79-6-3 record. He battled demons outside of the ring, however, and was sentenced to seven years in prison in 2007 on a burglary charge, of which he served just a year.

After the shooting, friends and former colleagues remembered the man they called "Macho" fondly (from the Associated Press via ESPN):

"He was like a little brother who was always getting into trouble," said former featherweight champion Juan Laporte, a fellow Puerto Rican who grew up and trained with Camacho in New York.

Even Don King weighed in:

"The Macho Man was a promoter's dream," renowned promoter Don King told AP. "He excited boxing fans around the world with his inimitable style. He was a nice, amiable guy away from the ring."

It's a cruel reminder on a day like Thanksgiving of what we all truly have to be thankful for, and our thoughts go out to Camacho's family.
